I don't know the answer to your question but I have noticed that the speedometer in my 128i vert with Sport is not very accurate. I use a Garmin GPS and when you do not set a destination it shows the actual MPH. It disagrees with the speedometer by up to about 3mph but it is not a constant amount. It seems to be as little as 1 mph at slower speeds. I haven't figured it out exactly but it may be the biggest error at about 60 mph.
Given my observation, I doubt BMW tries to make a 1mph adjustment. I was surprised when I noticed the speedometer error. My Suzuki SUV has a much more accurate speedometer (that's nearly the only thing the bimmer is not better at, however).
